Abstract
The utility model relates to a spherical plastic cage used for the deep groove ball bearing and comprises a plastic cage provided with a pocket. The utility model is characterized in that: an interior contact arc is arranged between the two pockets on the plastic cage at the back of one side of the pocket; an axial grease hole through the plastic cage is arranged on the interior arc; the pocket center face of the plastic cage divides the volume at the two sides of the plastic cage equally; the grease hole is arranged at the center of the interior contact arc; the diameter of the grease hole is the one third to one half of the thickness of the plastic cage wall. The utility model has the advantages of stable operation, reducing imbalance, fully lubricating the bearing, low vibration, low noise and long service life.
Description
Technical field
The utility model relates to a kind of bearing retainer, particularly a kind of Deep-furrow Ball Bearing Using For Sphere Shaped Plastic Separator.
Background technique
Some slow-speed of revolution at present, many employing engineering plastics cages in the deep groove ball bearing of light load, it have in light weight, self-lubricating property good, the advantage of shock-resistant, antivibration and noise reduction, particularly its cost easy to process is low, but because the intensity of engineering plastics cage is low, has no idea to make two chip architectures, make it that good balance can be arranged in the bearing steel ball both sides, therefore in operation process, cause the phenomenon of deflection on one side, produce very big unbalanced force.When bearing injects lubricating grease in addition, because stopping of engineering plastics cage makes lubricating grease can not well enter into bearing inside, inject lubricating grease on the both sides of bearing respectively, the efficient of production is very low.
Summary of the invention
The purpose of this utility model is the existing the problems referred to above of deep groove ball bearing that solve the available technology adopting engineering plastics cage, and a kind of Deep-furrow Ball Bearing Using For Sphere Shaped Plastic Separator that can overcome above-mentioned shortcoming is provided.The utility model design Deep-furrow Ball Bearing Using For Sphere Shaped Plastic Separator, comprise the plastic cage that has the pocket hole, it is characterized in that: between two pocket holes on the plastic cage of pocket hole one side, the inscribe arc is arranged, the greasing hole of axial perforation plastic cage is arranged on the inscribe arc.Two Side Volumes of branch plastic cages such as the pocket hole circle heart face of plastic cage.The greasing hole is positioned at the center of inscribe arc, and the diameter in greasing hole is 1/3～1/2 of a plastic cage wall thickness.The utility model has the advantages that retainer can be operated steadily, to reduce unbalanced force, make bearing lubrication more abundant, low vibration, low noise, long lifetime.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model,
Accompanying drawing 2 is the AA cross-sectional view of Fig. 1 of the present utility model,
Below in conjunction with drawings and Examples the utility model is elaborated:
Embodiment
Comprise the plastic cage 2 that has pocket hole 1 among the figure, it is characterized in that: in 1 in two pocket holes on the plastic cage 2 of pocket hole 1 one sides inscribe arc 3 is arranged, the greasing hole 4 of axial perforation plastic cage 2 is arranged on inscribe arc 3.Two Side Volumes of branch plastic cages 2 such as pocket hole 1 center of circle face of plastic cage 2.Greasing hole 4 is positioned at the center of inscribe arc 3, and the diameter in greasing hole 4 is 1/3～1/2 of plastic cage 2 wall thickness.Owing on the plastic cage 2 of pocket hole 1 one sides, inscribe arc 3 is arranged at plastic cage 2, plastic cage 2 volumes of two avris that just can guarantee pocket hole 1 center of circle face of plastic cage 2 equate, therefore in the bearing high speed operation, can keep the rotary balance of plastic cage 2, make bearing can hang down vibration, low noise, long lifetime high speed operation.On the inscribe arc 3 of plastic cage 2, have simultaneously the greasing hole 4 of axial perforation plastic cage 2, can make that just to satisfy both sides at bearing single face oiling fat lubricated, save both sides oiling fat make lubricate more abundant.
